Zin asked about a KS to monitor available space on a UNC. I modified a KS I had which verifies a UNC exists so that it would do this. The KS only allows you to check and monitor 1 UNC (but could be modified to do more).
The first thing it will do is verify the share exists and can be accessed. Assuming it can, then optionally it will check available space. If the available space is less than the threshold in MB/GB OR the available percentage is less than the threshold then you get an alert.
Optionally you can collect data on free space, and percent available.
